What causes this?

However, many set-top box remote controls, often those from Comcast, DirecTV, and DISHNetwork, are set to receive RF (radio frequency) signals by default.

Because the set-top box is set to receive RF signals, it is unresponsive to IR commands that are coming from the Slingbox IR blaster device. Fortunately, the fix is simple. By switching your remote settings from RF-type signals to IR-type signals, you can ensure that your remote commands reach your Slingbox.

Here's how to do that:

Comcast set-top boxes

Using the set-top box remote control, go to the set-top box Main Menu by pressing MENU twice.

Scroll down to Setup. Press OK/Select.

Scroll down to Cable Box Setup. Press OK/Select.

Scroll down to RF Bypass. Use either the Left or Right button to change this setting to ON. Press OK/Select.
